. ll This invention relates to a washing machine and more particularlyto a washing machine for hollow or tubulartmembers such as waterglasses.

An object of the invention is to provide a rotatable brush, driven by afluid pressure, which is automatically controlled by the application ofthe article to be washed :on "the brush.

Another object of the .invention is to provide -aplurality of adjacentbrushes,, rotatable in opposite directions, for cleaning the externaland internal surfaces of an article such as a water glass.

.A further object of the invention is to provide a mot-or, `driven by acleaningfluid under pressure, for rotatably driving a plurality ofbrushes and to control the flow of fluid through the motor, by a valvemeans operable by engagement of the article to be cleaned on one of thebrushes.

Other objects and advantages of the invention will more fully appearfrom the following description taken in connection with the accompanyingdrawings in which- Fig. 1 is a sectional View of my improved deviceshowing an embodiment of my invention; and

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1 on enlargedscale.

Referring to the drawings I have shown a motor housing i having a rotorchamber i2. The chamber i2 is elliptical and receives a rotor i4 havinga diameter substantially square to the dimension of the minor axis ofthe elliptical chamber !2. A cover plate IB is provided to close theopen side of the chamber |2 and to position the rotor l4 in the chamber[2. The opposite faces of the rotor are in sliding engagement with araised boss l8 on the bottom Wall of the chamber i2 and an inwardlyprojecting boss 20 on the cover IB. The bosses 18 and 20 are ellipticalas shown by dotted lines in Fig. 2 and the major aXes thereof are ofless dimension than the diameter of the rotor l4. There is providedbetween the wall of the chamber !2 and the bosses [8 and 20 anelliptical track or groove which receives a plurality of blades 22. Theblades 22 are received in radially extending slots 24 which are spacedcircumferentially in the rotor l l.

A tubular member 25 is journaled in the cover !6 and the bottom of thehousing and is fixed to the rotor i4 so that rotation of the rotor l4causes rotation of the tubular member 28. The outer end of the tubularmember 26 detachably receives a stem 28 of a brush 30. The stem 28 isprovided with a longitudinal passage 32 having a valve seat 34 at itslower end. A valve rod 36 is guided .in the passage 22 and ;projectsou'twardly above the ?brush 30. .A spring BBabutting \an .apertured.shoulder, '4.0 .in the ,.passage 3'2 and 'the outer end of 'the rod,.urges the rod 36 ou'twarly normally closes the passage 32 from the tube'2B by a valve '42 on therod'iifi 'Seating against the valve seat '34( 4Below 'the valve '42, .and ;carried by 'the rod 30, asleeve valve44inormally closing 'lateral open- 'ings '46 'in the tube 2.5. Thesleeve valve 44 'is provided with an opening 48 [for the paissage 'ofthe cleaning fluid therethrough.

'Cleaning fluid 'under ,pressure is admitted to 'the motor through aninlet pipe 50 and 'branched passages 52 and 54. The fluid pressure at'opposite sides of the rotor l4 causes rotation thereof in a directionindicated by the arrows in Fig. 2. Exhaust fluid is received in outletpassages 56 Which are connected to the bottom of the tube 26 by passages58.

When the parts are in the position as shown on the drawing the fluidpassage 46 is closed thereby preventing a flow of fluid through the pumpand consequently the rotor i4 is Stationary. When the valves 42 and 44are opened such as by pressing the rod 36 inwardly, the dischargepassage 46 is opened permitting the fluid to flow through the system androtate the brush 30 driven by the rotor l4 and tube 26. Ordinarily therod 36 is operated by the application of a water glass over the brush30, the bottom of the glass engaging the outer end of the rod 36 and aslight pressure downwardly permits the fluid to discharge into thehousing 60. A portion of the fluid is conducted through the passage 32and discharged at the top of the brush 30, inside the glass drainingover the brush 30 into the housing B0.

The housing 60 is detachably secured to the motor housing [0 by Screws62 with a gasket 64 between the housing IO and the housing 60. Anoverflow pipe 65 has been provided for discharging the fluid from thehousing 00 and is of a 4 predetermined height to maintain a constantfluid level within the housing 60.

The tube 26 carries a gear 68 which meshes with gears 10 and 12 atopposite sides of the gear 68;., The gears '10 and '12 are drivinglyconnected brushes 14 and lG respectively. Rotation oi\ he brushes are inopposite direction to the direction of rotation of the brush 30. Thebrushes 14 and 1B clean the outer periphery of the water glass when thelatter is placed over the brush 30. The brushes 14 and 15 are journaledin an overhanging projection 18 of the cover plate i6 and a removableplate 80 which is secured to the projection 18 by screws 82. A spacer 84positions the removable plate 80.

If it is desired to add a solvent or soap solution to the cleaningfluid, a container 86 may be seits scope other than by the terms oftheappended I claims.

I claim: 1. A washing device comprising a fluid motor 2. A washingdevice comprising a fluid motor housing having inlet and outletpassages, a tubular member journaled in said motor housing, a rotormounted in said housing and carried by said tubular member, said tubularmember'projecting outwardly beyond said housing, a gear mounted on saidtubular member external of said housin a pair of gears rotatably mountedon said housing and in driving engagement with said first named gear,the outer end of said tubular member having radially extending openings'through its side wall,

- a valve for controlling the openings in said tubuhaving inlet andoutlet passages, a tubular member journaled in said motor, said motorhaving a a rotor carried by said tubular member, said motor outletpassage communicating with one end of said tubular member at one side ofsaid rotor, said tubular member having an outlet passage at the oppositeside of said rotor, a rotatable brush carried by said tubular member, avalve for the outlet passage in said tubular member, said brush havingan axially extending passage therethrough, a valve for said axiallyextending passage, a rod extending through said axially ex-` tendingpassage projecting beyond said brush and carrying said valves, androtatable brushes adjacent said first named brush and rotatably drivenby said rotor.

lar member, a second tubular member forming an extension of said firsttubular member and communicating therewith, a valve for controlling thecommunication between said tubular members,

'said valves being connected togethenan axially extending rod projectingthrough the outer end of said second tubular member for moving saidvalves, and brushes rotatably driven by said gears.
